<H2>Flash SMS</H2>On some phones (all Nokias, some Siemens, Ericsson, Motorola 
etc..) a class 0 message will appear as a flash SMS message. These messages 
appear on the screen immediately upon arrival, without the need to press any 
buttons on the phone. If the data coding scheme is set to 16-bit unicode (ucs2), 
and the message starts with "0001", it will appear as a blinking flash message.
